"For the pm dimming se 211111tneraiel l d v ,position .when it is' out o! contact with the ironer rollhereinafter .to be described, I provide a leaf spring 30 having its upper end secured to shoe 22 as by boltiand having its .lower end ln eilgagernent with the lower end of yoke 7. l

. In the boss 3 is secured en outwardly extending tubular shaft 32.' Aironet-roll 33 is-.Jouir'utled onshaft 32 byy means' of a bearing 3g adjacent its innerV end .and with a similar bearing not For the purpose of operating tubular shaft 6 to effect operation of ironer shoe 22, I provide 0n shaft 39 a worin gear 40 rotatably mounted on shaft 39. Worm gear 40 is in mesh with a worm 41 carried on the armature shaft of a motor 42 which, for convenience, is mounted in a vertical position on gear casing'l.

On shaft 39 is rotatably mounted a cam member 42 which is positioned in the open end of jaw arm 43. The other end of jaw arm 43 is secured to the inner end of shaft 6, as by a pin 44. On the side of cam member 42 which faces worm gear 40 is pivotally mounted a clutch dog 45 as by a pivot pin 46.

On the hub 47 of worm gear 40 is secured, as by a pin 48, a clutch member 49 provided on its periphery with spaced recesses 50 adapted to receive a finger 51 carried on dog 45.

A spring 52 has one end secured to cam member 42, as by a pin 53, and has its other end secured to dog 45 to normally move dog 45 about its pivot to bring finger 51 into registration with a recess 50.

When dog 45 on cam 42 is in registration with clutch member 49, the cam 42 will be operatively connected to the worm gear 40 so that the rotation of such gear 40 will cause the rotation of cam 42.

The rotation of cam 42 will cause an oscillating movement of jaw arm 43, which oscillating movement will be transmitted to shaft 6.

For the purpose of holding dog 45 out of registration with clutch member 49 so that cam member 42 will be at rest, I provide an arm 54 having a' U-shaped upper end provided with round apertures through which the inner end of a shaft 55 extends so that member 54 is free to rotate on shaft 55.

Shaft 55 is journaled in a bearing 56 in gear casing 1. 'I'he outer end of shaft 55 is secured as by a pin 57 to an operating handle 58.

The lower end of member 54 is U-shaped and is adapted to be moved into and out of the path of movement of dog 45. When member 54 is in the path of movement of dog 45, such dog 45 will be held in spaced relation to clutch member 49 with finger 51 out of registration with apertures A hook-shaped member 59 has its lower end I positioned between the opposed faces ofthe upper end of member 54, shaft 55 extending through an out of round aperture in member 59 so that member 59 and shaft 55 are locked against relative rotary movement.

path of movement of dog 45.

As perhaps may best be seen from Figure 5, a spiral spring 60 has one end secured to casing 1 and has the other end secured to the upper end of ,member 59 to normally cause member 59 to be moved about its pivot, such movement being limited by the contacting of the upper end of member 59 with casing 1.

When member 59 is in this position the lug 59 is in a position to permit member 54 to be moved above its pivot and into the path of movement of dog 45.

A spiral spring 54 has one end secured to casing 1 and has the other end secured to the upper end of member 54 to normally urge the latter .magnet 61 and out of the path of movement of I have here shown diagrammatically a wiring diagram and a switch 62 for magnet 61, no source of potential being indicated, but it will be understood that any desired type of switch may be utilized, although I prefer to use a foot operated switch so that the magnet 61 may be energized by a foot, leaving the hands of the operator free.

In order to insure that the dog 45 will be moved a suilicient distance about its pivot 46 when it contacts with member 54 so that 5l will be moved in spaced relation to clutch member 49, I employ an arrangement of parts which may best be seen from Figures 6, 'I and 8.

A plate 63 is pivotally mounted on pivot pin 46 and conforms in shape and position approximately to dog 45. One end of plate 63 is bent as shown at A on Figure 8 to a position in spaced relation to the end of dog 45.

A spiral spring 64 is interposed between the end of plate 63 and the end of dog 45. The upper edge of plate 63 is also bent outwardly as shown at b on Figure 8 above the upper end of dog 45 to limit the upward movement of dog 45 with reference to plate 63 under the action of spring 64.

The spring 52 heretofore described is secured to the end of plate 63 in opposed relation to spring 64. When the member 54 is in the path of movement of plate 63 and the same is brought into contact therewith, the spring 64 will be compressed' and the dog 45 will be raised to carry finger 5l out of registration with clutch member 49. The spring 64 will then expand to carry dog 45 further about its pivot 46 to position the finger 51 in spaced relation to the clutch member 49 so that there will be no possibility of the two contacting while the clutch member 49 continues its rotation.

I'he movement of plate 63 and dog 45 takes place when the end of plate 63 to which the spring 52 is attached contacts with the member 54. If the opposite end of plate 63 contacts with member 54, the same movement of parts will take place due to the fact that such end of plate 63 is held against further movement which will cause plate 63 to be moved about its pivot to compress spring 64 and move dog 45 about its pivot to carry nnger 51 out of registration with clutch member 49, after which spring 64 will expand to move dog 45 further about its pivot 46 to carry finger 51 to a position in spaced vrelation to clutch member 49.

For the purpose of imparting rotary movement to the roll 33, I provide a gear 65 rotatabLv mounted on shaft 39. One face of gear 65 is provided with circumferentially spaced clutch teeth 66 adapted to engage opposed clutch teeth 67 provided on one face of gear 40.

As described in my before-mentioned application Serial No. 410,484, shaft 39 is adapted to be moved intermittently axially by means of a key 68 in shaft 39 which bears against a cam surface 69 on the inner end of bearing 38.

A further description of the operation just described is not essential to a description and explanationpf my invention `ic rected to the operation of .c ftrols the ironing shoe.. v Adjacent boss 3 andin casing with gear 65.

Operation When it is desired to operate the machine, the heating unit 23 in shoe 22 is connected to a source of potential by means of a lead 73. 'I'he switchcontrolled motor 42 is then connected, and rotary motion will then be conveyed in the manner and through the gearing above described to the gear 40 and thence to the roll 33.

'I'he clutch dog 45, not being operatively connected to the clutch member 49, the cam 42 will not rotate. The cam 42 is eccentrically mountedon shaft 39 so that the rotation of the same when eil'ected will cause an oscillating movement of member 43 as the high side of cam 42 alternately contacts with the opposed jaw ends of member 43. v

With the parts in the positions shown-in Figure 2, the high side of the cam 42 is in contact with the lower jaw of member 43 so that the inner end o1' member 43 is in the fully depressed position. In this position, the shaft 6 will have been rotated in an anti-clock-wise direction to the fullest extent and this movement will have carried the shoe 22 into pressure engagement withr the roll 33.

If desired, the parts may be left inl this position and the articles to be ironed introduced between the shoe 22 and the roll 33. The roll 33 rotating the article will be carried downwardly between the shoe 22 and theroll 33. If it is desired to move the shoe 22 away from roll 33 to permit of more careful arrangement of the articles to be ironed before the actual ironing operation, the member 54 by the use of handle 58 or preferably switch 62 will be moved out of the path of movement of dog 45 so that finger 51 will engage clutch member 49 to cause the rotation f cam 42.

The handle 53 or the switch 62 having been immediately released, the member 54 will return into the path of movement of the dog 45 so that the dog 45 will be stopped and moved out of engagement with clutch member 49 as soon as cam 42 has completed a half lrevolution. When this has taken place, the high side of cam 42 will be in contact with the upper jaw of member 43 so that the inner end of member 43 will have been raised to the highest position with the result that the shaft 6 will have been rotated to the fullest extent in a clock-wise direction to carry the shoe 22 out of engagement with the roll 33.

When it is again desired to have the shoe 22 come'into ironing relation with the roll 33, the handle 58 or the lswitch 62 is again manipulated to move member 54 out-of the path of movement of dog 45 to permit the latter to engage the clutch member 49 to cause the rotation of cam 42. This n intermittent operation of shoe 22 maybe continued as desired.

It sometimes happens that the motor 42 is suddenly and unexpectedly cut off from the source of potential as, for example, by the blowing of a '75 fuse and if this takes place when the shoe is in ,might 'bs .scorhedpr ,.isibu'meled a., i shaft '70 having on its inner-endagear 'lllinmesh 3- ur'elofacilwiththe roues any artinewhicn between r them would probably be burnedy due-to thefact that the heatlelement L23. and the lslice 22 will retain their heat for, some time, and inasmuch as the roll 33 .80 .I will have ceased to, rotate, the article will beheld `'I'he outer end ofshaft .'10 cari-lesa gearl'YlZin- .I mesh with internal gear 35, With, gear v65 in. clutching engagement Withgear 4Q, the continuing j rotary motion of gear 40 will becommunicated to gear and will thence through gear 311,1'sljiafft'10,, gear 72 and gears 35 becommunicated to'roll 33.@

between-itand the shoe 22. In v.order to provide ay means; whereby the .shoe

` 22xriayvzbe moved'away f rom the roll 33irrespective ofthe operating mechanism just described, I vhave provided the shoe support heretofore described so .that in case of emergency, the operator may move the handle L20 to pivot bell crank 19 and cause dog 16 to be moved about its pivot to carry hook 17 out of engagement with pin 11 andv break the connection between yoke 7 and member 8 so that yoke 7 carrying shoe 22 may be moved outwardly from the roll 33.

In order to limit this outward movement oi' yoke 7, I provide on yoke 1 a laterally extendingl pin '74 adapted to contact with a lug 75 on member 5.

As disclosed in my above referred to application Serial No. 398,386, a means is provided whereby the yoke 7 will automatically be again locked to the member 8 when the machine resumes its operation, but inasmuch as an understanding of such means is not essential to the understanding of the invention disclosed in this application, I will not describe it in detail.

It will be understood that my invention is adapted to be used with various types of ironing machines and it will also be understood that the exact -arrangement of parts here disclosed may be varied to a considerable degree without departing from the spirit of my invention for although I have shown and described a specific structure and form and arrangement of parts as an exemplication of an embodiment of my invention, I

do not desire to restrict myselfto the exact size, B5
